Our water is safe for all pets to drink except for fish, reptiles and amphibians that live in water. Animals that live in water take water directly into their bloodstream through their gills. For this reason, the disinfectant must be removed before adding water to fish bowls and aquariums. Consult your local pet store for the appropriate neutralizing chemical. Ensure that the product says that it will neutralize "Chloramines" and "Chlorine".
